STUDY OF BLACK HOLE 

Black hole can be characterised by three quantity - mass(schwarzschild) , angular momentum and electric charge . If there no  electric charge and no angular momentum then it is named as schwarzschild black hole .If there is angular momentum and no electric  charge then it is named as kerr black hole . If black hole has both electric  charge and angular  momentum then it is known as kerr-newman black hole . 

Charged black hole possesses the electric charge . Electromagnetic compresses an electrically charge mass greater than the gravitational attraction .Charge in black hole attracts opposite charge particle  . In the sense the charge in black hole is neutral  . The motion of black hole is detected by its angular momentum .Angular momentum is constant it  never changes .Angular momentum is given as m*v*r . Angular momentum of an black hole is based on  topalogically massive and new massive gravity theories . Schwarzschild radius is also called as gravitational radius. Schwarzschild radius of earth is 1 inch approximate ,radius of sun 3 km . 

THERE ARE TWO WAYS TO DETECT AN BLACK HOLE :- 

1 BY gravitational influence  as black hole grow their intense gravity pulls matter towards them the matter heats up to scorching  temprature .

2 when matter falls into black hole it heats up as it plung to  its doom .Before it passes into the black hole and is lost foever . 

BLACK hole is formed when nuclear fussion which powers star will burn ,then gravity and whatever left after fussion will collapses togather. After this star exploses to supernova the remaining matter is so dense that whatever cames to it goes forever .

There are two types of black hole rotating black hole and non rotating black hole .The non rotating black hole has singularity as point .The rotating black hole has singularity as circle . If we know the electric charge , angular momentum , mass , We can describes the all characteristic and all quantities of black hole.

If we will plant trees on mars,
Then we can control the limit of CO2 and increase the amount of O2 and we can live there

can we destroy black hole by using of hawking rays?

The only problem in Atharva Talatule's idea is planting trees on mars. The soil there is very icy and powdery which is not ideal for plant growth

If something goes inside a black hole what happends to it ? Whether it is destroyed or black hole is a type of pathway between 2 cosmic points in a universe or might be multiverse

Why can't we say that the universe started at a black hole singularity?

What happens to the matter contained in a black hole?

Is BIG BANG theory a hypothesis?
